The average of the fraction of students on both classes who went on the field trip is; 13/20.
What is a fraction?A fraction represents a part of a number or any number of equal parts. A fraction is a ratio of two integers called the numerator and denominator.
Given that the sum of the fraction of both students in the two classes is;
3/5 + 7/10
We know that the LCM of the denominators which are 5 and 10 is 10
Therefore, the sum of both fractions = 6/10 + 7/10 = 13/10
The average = 13/10 /2 = 13/10 x 2
The average = 13/20
Therefore, the average of the fraction of students on both classes who went on the field trip is; 13/20.

A uniform continuous distribution has a maximum of 14 and a minimum of 2. Samples of size 36 are drawn from the distribution. What is the variance of the sample means?.
The variance of the sample means will be 0.3428.
What is Variance of sample means?
The variance of the sampling distribution of the mean is the population variance divided by the sample size.
Given that;
A uniform continuous distribution has a maximum of 14 and a minimum
of 2.
Samples of size 36 are drawn from the distribution.
Now,
The population variance = 14 - 2
= 12
And, Sample size = 36
Since, The variance of the sample means is defined as;
= Population variance / Sample size
Substitute all the values, we get;
= 12 / 35
= 0.3428
Thus, The variance of the sample means will be 0.3428.

How to Solve for the Formula for a Variable?
Solving for the formula for a variable, means we should make the variable the subject of the formula by isolating the variable to one side of the equation to determine its value.
Given the equation of the formula, A = yn + y, to solve for n, follow the steps below:
A = y(n + 1)
Divide both sides by y:
A/y = y(n + 1)/y [division property of equality]
A/y = n + 1

Answer: Cannot, 12 foot , 2 feet
Step-by-step explanation:

The carpenter can cut the 12 feet wood by 2feet to make triangular frame.
What is triangle?A polygon with three vertices and three edges is called a triangle. Geometry's most fundamental shape is this one. Triangle ABC is a triangle with A, B, and C as its vertices.
Any three non-collinear points can create a unique triangle and a unique plane in Euclidean geometry (a two-dimensional Euclidean space). To put it another way, every triangle is contained in some plane, and there is only one plane that contains that triangle.
Given Carpenter has three pieces of wood measuring 5 feet, 6 feet, and 12 feet.
and wants to make a triangular frame,
with these wood pieces he can not make the triangular frame because it does not follow the property of triangle,
which says the sum of two sides of triangle should always greater than the larger side,
here large side is 12 feet and 5 + 6 is less than 12,
so to make a triangular frame he should decrease the larger side which should be less than 11
by cutting 12 feet piece by 2 feet it will be 10 feet and carpenter can make the triangular frame.
Hence the carpenter need to cut 12 feet long piece by 2 feet, to make triangular frame.

How to solve equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
Therefore, the equation can be solved as follows;
[tex]\frac{2k-3}{k+9}=\frac{3}{5}[/tex]
cross multiply
5(2k - 3) = 3(k + 9)
10k - 15 = 3k + 27

10k - 15 = 3k + 27
10k - 15 + 15 = 3k + 27 + 15
10k = 3k + 42
subtract 3k from both sides of the equation
10k = 3k + 42

peter deposited $7,790 into an account that earns 4 5/8% interest, compounded annually. calculate the interest peter will earn after 42 months. how much will peter have in his account after 42 months?
The interest earned by Peter after 42 months is $1,335.60 and the total amount in his account is $9,125.60.
How to determine the accrued ( A ) and interest ( I ) amount in a compound interest?The formula for compound interest is expressed as;
A = P(1 + r/n)^nt
Where A is accrued amount, P is principal, r is interest rate, n is compound, and t is time period.
Given the data in the question;
Principal P = $7,790Annual interest r = 4 5/8%Compounded annually n = 1Time t = 42 monthsAccrued amount A = ?Interest I = ?First, convert the interest rate to decimal.
Rate r = 4 5/8% = (4×8 + 5 )/8%
Rate r = 37/8%
Rate r = 4.625%
Rate r = 4.625/100 = 0.04625 per pear
Next, convert time from months to years
Time t = 42 month = ( 42/12 )years
Time t = 3.5 years
To determine the accrued amount, plug the given values into the compound interest formula and solve for A.
A = P(1 + r/n)^nt
A = $7,790(1 + 0.04625/1)^( 1 × 3.5 )
A = $7,790(1 + 0.04625 )^( 3.5 )
A = $7,790(1.04625 )^( 3.5 )
Accrued amount A = $9,125.60
Note that; Accrued amount A = Principal P + Interest I
Hence;
Interest I = A - P
Interest = $9,125.60 - $7,790
Interest = $1,335.60
Amount in the account after 42 months is the same as the accrued amount A, this is $9,125.60.
Therefore, the interest earned is $1,335.60 and the accrued amount is $9,125.60.

A baseball team won 16 of their first 20 games. If they win half of the rest of their games, how many more
games will they have to play in order to win 75% of the total number of games?
The least number of games the team must win to raise its winning record above 75 percent is -4 , by raising the win fraction to the total number of fractions as 36/48.
What is meant by fractions?There are ratios of fractions that represent a portion of the whole. A fraction has the form a/b, which may be read as "a by b," and it has the function a divided by b. The denominator is referred to as b, and the numerator is known as a.
To transform a percentage to a fraction, we divide it by 100.
Given that a baseball team has won 18 of the 30 games it contains played during the season.
We exists asked the least number of games the team must win to raise its win record above 75%.
Let the number of games needed to be x.
The new number of wins will be the sum of current wins and the games to win, that exists, the new number of wins = 16 + x.
The new number of games played will be the sum of current games played and the games to win, that exists, the new number of games played = 20 + x.
Therefore, the win fraction of the team can be shown as the ratio of the total wins to the total number of games played, that exists, the win record = (16 + x)/(20 + x).
We exists asked to make sure that the win record should be at least 75%,
This percentage can be described as the fraction 75/100 = 3/4.
Therefore, we get the equation:
(16 + x)/(20 + x) = 3/4,
simplifying the above equation, we get
4x - 3x = 3x - 4x - 4,
x = -4.
Therefore, by increasing the victory fraction to the entire number of fractions as 36/48, the team just needs to win -4 games to improve its winning percentage above 75%.

area of the circular tabletop = the area of a circle
area of the circular tabletop = π r²
Here r = 3 feet
area of the circular tabletop = π (3)²
area of the circular tabletop = 9π
area of the circular tabletop = 28.27 square feet

What are the equations of motion?
Kinematics equations of motion define the fundamentals of an object's motion, such as its position, velocity, or acceleration over time. These three equations of motion control how an item moves in one, two, and three dimensions. It is possible to determine components like displacement(s), velocity(initial and final), time(t), and acceleration(a) using one of three equations of motion (a). The three equations of motion are as follows:
First equation: v = u + at
Second equation: s = u*t + 0.5t²
Third equation: v² = u² + 2as
Given, the initial velocity of the skydiver = 3 m/s
Height of fall for the skydiver = 1200 m
Also, after reaching ground, final velocity of the skydiver = v = 0 m/s
Let the time taken to reach the ground be = t
Therefore, using the first equation, we have
0 = 3 + (-9.81)t ⇒ t = -3/-9.81 = 0.305 s
Thus, time taken for them to reach the ground is 0.305s.
